Ifthe diameter of each gear i) is equal to that of the gear a on'tlieeranlc-sha H, the speed of the latter reduced in the ratio of 23 1 isimparted to the cylinders. For example it the eranleshail t runs at1,800 revolutions per minute the speed of the cylinders and of thepropeller connected therewith will be only 600 revolutions per minute.The cylinders and crankshaft here rotate in opposite directions. Aseonipared with known internal combustion engines whose t- 'liudersrotate at the same speed as the rranlc-slniit't we obtain the ver; greatadvantage that there is a great reduction in elleet on the eylinders ofcentrifugal force and of the lateral pressure ol. the piston whichmaterially all'eels the life of the on nine, both oi which fol-(esincrease as the square of the speed and cause motors con strurted forvery high speeds to be danger onsand the eouslruelit'm of those of aspeed above a (-ertuin liuiil impossible. Furthermore, .loitheparticular purpose of the inreution there is the great advantage thatthe same low speed as eieui-y than a high-speed opeller.

this the cylinders are utilized well Ll'tllll mine to the pistons beingable to work at the highest possible speed. For by suitably choosing theratio of transmission between the erank-sliuii't and cylinders itispossible to arrange for as many ignitions as desired during onerevolution of the cylinders. It the deser bed engine has, for example, alouir-slroh'e cycle, when the ratio of transmission is 3 :1 there willbe two explosions per revolution. 111 general, the number of explosionsI when A is again the gear ratio and in this case equals lieferriug newto Figs. 3 and 4. a fivecylinder, four-stroke cycle engine is shown inwhich the brushes k, andh,, connected in parallel and to the samemagneto M, conduct the current from the latter to one of the slidingcontactpieces 1 to 5, and thence to the corresponding spark-plug 2' 2'e,, a, or z, of the cylinders a, to 2,. Instead of magneto ignitionbattery ignition may, of course, be employed. During one half revolutionof the contact-ring when each cylinder is fired once, the brus it, makesthe connection, while durin the other half revolution, when a seconignition occurs in each cylinder, the brush h supplies the current.

Our invention is not limited in its application-to a particular numberof c .linders, nor toany particular number of ignitions per revolutionof the cylinders; Fig. 4 shows the distribution of contact-pieces. forthree ignitions per revolution of the cylin-' ders of a five-cylinderengine. For a: ignitions the contact-ring will be divided into a: partsand :1: times it sliding contact-pieces will be provided. The spacebetween two working of fixed contactieces will be divided by the numberof cylinders, in the example by five,

and the order of ignition will be arranged as desired. Theremaining w-lportions will remain without. contacts.

The described ignition distributer is erected exceedingly simply,because the distributing ring 9 together with the brushes orcontact-pieces h k 72. need not be driven by special gearing to make itoperate correctly, but can be simply connected directly with therotating cylinders or with their sup orting frame. Slip-rings forconducting t e current from the contact-ring g to the sparkplugs or fromthe contacts h to the magneto are therefore unnecessary. This is a greatadvantage, for otherwise the certainty of the motor, especially with alarge number of cylinders, would be seriously endangered.

By means of the arrangement illustrated in Fig. 1 one of the greatestdrawbacks arising from the use of rotating cylinders, viz, the large oilconsumption, is obviated, because the centrifugal force which in otherengines throws the oil. into every corner of the casing, from which itcannot be recovered, is here used for positively returning crank-pin andmeans of an oil-pump 0 into the hollow crank-shaft w. This can be doneby driving the oil-pump by means ofa second shaft. Fromthe crank-shaftthe oil asses to the to thebearings o the connecting-rods. After leavingthese it is flung' from the oil-throwers 1' into the ring t rotatingwithin the casing, passes outward right and left through holes 7 and isfinally delivered by throwers to into channels '0 in the stationaryportion of the casing. It

flows thence from the lowest points through pipes I back to the oil,vessel m. It is immaterial for 'the oil distribution whether thecrank-shaft rotates as in the illustrative embodiment, or whether it isstationary.
